3.3.26 SWEEP Key (Sweep Time)
Pressing the SWEEP key displays the SWEEP menu.
MNL allows you to specify a sweep time.
SWP Time AUTO/MNL
Toggles the sweep time between AUTO and MNL.
AUTO:
Automatically sets the optimum sweep time according
to the span, resolution bandwidth and video bandwidth.
MNL:
Sets the sweep time manually.
NOTE:
When the sweep time is equal to or less than 9
ms, the trace point is set to 501, and the detec-
tor is set to the sample detection mode
(OPT29).
Auto All
Automatically sets the resolution bandwidth, video bandwidth
and sweep time according to the span settings.
Trig Delay
Sets the delay time in reference to the trigger point or sets the pre-
trigger time.
This is available only when the zero span is selected.
Gated Sweep
Displays the Gated Sweep menu and two windows.
The upper screen displays the result of gated sweep, while the
lower screen displays a gate signal, the gate position and width.
Gate Source
Displays the Gated Source menu.
The trigger conditions for a gate signal in the gated sweep mode
can be set.
Ext
Sweep is synchronized with external trigger signals.
TV-V
Sweep is synchronized with vertical synchronous signals of TV
signals.
TV-H
Sweep is synchronized with horizontal synchronous signals of TV
signals.
Slope (TV Polarity) +/-
Switches polarities b and - for the trigger slope or video
modulation of TV signals.
+:
Sweep is started at the rise of a trigger.
In the TV trigger mode, sweep is started synchronously
with a video modulation signal of + polarity.
-:
Sweep is started at the fall of a trigger.
In the TV trigger mode, sweep is started synchronously
with a video modulation signal of - polarity.
